Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Leica V-Lux 4 and Leica V-Lux 3 side-by-side from the front, back and top in their relative dimensions. Leica V-Lux 4 has external dimensions of 125 x 87 x 110 mm (4.92 x 3.43 x 4.33″) and weighs 588 g (1.30 lb / 20.74 oz) (including batteries). Leica V-Lux 3 has external dimensions of 124 x 81 x 95 mm (4.88 x 3.19 x 3.74″) and weighs 540 g (1.19 lb / 19.05 oz) (including batteries).
Below you can see the front view size comparison of Leica V-Lux 4 and Leica V-Lux 3. Leica V-Lux 3 is clearly the smaller of the two cameras. Its body is 1mm narrower, 6mm shorter and 15mm thinner than Leica V-Lux 4.
Here is the back view size comparison of Leica V-Lux 4 and Leica V-Lux 3.
Now lets look at the top view comparison of Leica V-Lux 4 and Leica V-Lux 3.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Leica V-Lux 3 is 48g lighter than the Leica V-Lux 4 but we don't think this will make a significant difference.
Unfortunately neither Leica V-Lux 4 nor Leica V-Lux 3 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Bridge Cameras with Weather Sealing
